<> " It seems to be at the intersection of ideas behind reshape / stack" -reshape- does indeed look like a great solution here, but really your dataset is neither exactly "long" nor "wide"... -stack- seems a little far fetched. I rarely try to use it for this kind of data management problem...

Dezember 2009 23:35 To: statalist@hsphsun2.harvard.edu Subject: st: combining values distributed over multiple observations Hello - this seems like an exceedingly simple question, but couldn't find a reference to relevant syntax in the help. What I'm essentially trying to do is go from the below format, where a given variable "A" takes different values at discrete observations arrayed over T1-T5: var T1 T2 T3 T4 T5 A .129 . . . . A . .647 . . . A . . .991 . . A . . . .582 . A . . . . .043 to the following format, wherein all values of A at each time are compressed into one observation : var T1 T2 T3 T4 T5 A .129 .647 .991 .582 .043 It seems to be at the intersection of ideas behind reshape / stack (and even stjoin - except it's not survival-time data). Yet doesn't fall neatly within any (or does it?)
